Remote ControlCircuit Through RF Without Microcontroller
This circuit illustrates a remote control circuit diagram using RF technology without the use of a microcontroller. Features include a simple remote control circuit that operates via radio frequency.
The remote control circuit operates by transmitting signals through radio waves, enabling...
RF Remote Control Encoder and Decoder Chips Explained
Creating a universal remote control system has become quite straightforward. One can acquire the necessary chips, assemble them, and the high-tech remote control device will be operational. This document discusses specific remote control chips designed for this purpose. The IC...
Simple RF Power Meter
Many beginners trying out their skill with QRP TX for the first time have to overcome many problems before they are able to come on the air. One usual complaint is that everything is working fine, but the signal is...
SA607 SA607 Low-voltage High Performance Mixer FM IF System
The SA608 is a low-voltage, high-performance monolithic FM intermediate frequency (IF) system that includes a mixer, oscillator, two limiting intermediate frequency amplifiers, a quadrature detector, a logarithmic received signal strength indicator (RSSI), a voltage regulator, and audio and RSSI operational...
FM (prm) optical transmitter
The basic circuit operates at a frequency of 80 kHz, which is constrained by the combination of the PUT (Programmable Unijunction Transistor) capacitors. The maximum modulation frequency achievable is 60 kHz. The pulse repetition rate is directly proportional to Vin,...
Receiver for 50 khz optical transmitter
To achieve maximum range, the receiver should be constructed similarly to a radio receiver front end, as the signals received will exhibit comparable frequency components and amplitudes of the photodiode current. The primary limitation on the receiver's performance is the...
